ABSTRACT:
A loom-controlled leno or cross-weaving system, alone or in conjunction with tabby or ordinary weaving. The leno heddle is composed of two upright members, each connected to two flexible cross-members. Each upright member is connected to a separate, independently moving portion of the loom frame. Each cross-member has an eye in the middle for the passage of the warp thread. The upper cross-member is positioned below the lower cross-member when the warp threads pass through the eyes. Alternation of the elevation of the upright members causes the warp threads to alternate positions laterally. Leno weaving is achieved with a throw of weft for every alternation of upright member position. Tabby weaving is done using a rising loop and a falling loop, each connected to the loom frame independently. One warp thread goes through the eye of the upper cross-member and also through the rising loop. The other warp thread passes through the eye of the lower cross-member and the falling loop. When the loops are separated, the tabby weft is thrown.
